VB
Private Sub treeViewAdv1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) If e.Button = MouseButtons.Left Then ' Get the point where the mouse was left clicked Dim p As Point = Me.treeViewAdv1.PointToClient(Control.MousePosition) ' Get the node at the left click point Dim node As TreeNodeAdv = Me.treeViewAdv1.PointToNode(p) If Not node Is Nothing Then ' See if the label was clicked on If node.TextAndImageBounds.Contains(p) Then node.Checked =Not node.Checked End If End If End If End Sub
